DIMM memory upgrade

OldFoo · Post by **OldFoo** » Mon Mar 14, 2011 8:04 am

If I am going to upgrade my DIMM to 512 from 256 do I need to change the jumpers on the DIMM board? Does anyone know the correct configuration for 512 vs 256 on a NET DIMM.

thanks

Plug & Play. No need for any config changes.

I have 512 in my DIMM but only 256 is being recognized. I read on another post that Andy Geezer said there is some dip switches to change. But he didn't say which.

Here is the post where he says there is some dips to change when upgrading memory.

Anyone with a good 512 Dimm can take some pics of their dimm dip switches? Thanks

I am speaking from experience. I've upgraded to 512mb and I didn't have to change anything. There is a high likelihood that one of your memory modules is either not seated correctly or not working at all. Take out one of the dimm modules and power the system to see if 256mb is recognized. If all checks out, swap modules and repeat. One of them may cause an error. If no error occurs, then it is a 'seating' problem.

If, despite all of this nothing changes, let me know and I will post my jumper configuration.
